33. A method of performing epicardial coagulation on a heart in a patient, the method comprising:
accessing a diaphragm through a first incision in an abdomen of the patient;
advancing an access device through the diaphragm into a thoracic cavity of the patient where a distal end of the access device is advanced through the diaphragm adjacent to a posterior surface of the heart exterior to a pericardium surrounding the heart such that the access device separates an organ from the heart to forming a temporary cavity in the thoracic cavity, where the access device comprises at least at least one working channel; and
positioning a coagulation device into the thoracic cavity through the working channel and adjacent to an epicardial surface without dissecting any pericardial reflections; and
coupling a visualization system to the working channel; and
coagulating an area on the pericardial surface.
